New hemlock hybrids that are tolerant to the invasive insect known as hemlock woolly adelgid have been created by U.S. Department of Agriculture (USDA) scientists. Geneticist Richard Olsen and horticulturist Sue Bentz of USDA’s Agricultural Research Service (ARS) teamed up with Forest Service entomologist Mike Montgomery to breed and select these tolerant hybrids. Olsen and [...]
